Beware of printer streak lines

I have been using stickermule for quite some time and have been pleased up until this recent order. I ordered hundreds of labels and while the design file and proof look good, the labels I received have a red streak line horizontally across on all labels I received. It is extremely noticeable and ruined my project for my client to the point that I have had to use a different label printer. Be careful that even if your proof looks good, you still may receive labels that have errors like streak lines that you will only find out upon receipt. I would be happy to share a picture of the streaks on these labels I received though am unable to do so on this review.
